jQuery event triggering on all listeners

Question

I have a custom event I've made which I would like to trigger at some point with no relevance to selection. I.E - I would like to do something that would behave as running ``` $("*").trigger('customEvent'); ``` But jQuery documentation warns that using the universal selector is very slow. Is there a way to trigger all the object that are bound to a specific event without having to use the universal selector `$("*")`? Thanks! P.S - I'm currently using a specific `class` called `custom_event_listener` and use `$('.custom_event_listener').trigger('customEvent')` to avoid using a universal selector. I'm wondering if there is a way to avoid the use of a `class`.

Accepted Answer

You can trigger an event on everything that has a handler bound like this:

```
$.event.trigger('customEvent'); 
```

This loops through `$.cache` to find what actually has a handler, then fires on those elements...rather than just finding every element and firing the event on each one.
